I have an activity of register of "Invoices" that has 1 spinner. In this Spinner contains card registration with IDCard, title and description (being saved in a "Card" table in the database). When I save this "Invoices" record in the "Invoices" table, this spinner only saves the IDCard.
I have another activity that edits this register of Invoices, it has the same spinner, but I want this spinner to recover the position of the item to be edited, but I can not do this, does anyone have a solution?
Note: Can you get the position of the item from the IdCard? Sorry for my bad english.
Thanks in advance.

To complete the code, there are Models, if I need to put them here. I just put the essential code.
In InvoicesEditActivity.java I changed the getSpinnerIndex method to:
public int getSpinnerIndex(Spinner spinner, String myString) {
int index = 0;
for (int i = 0; i < spinner.getCount(); i++) {
HMAuxCartao model = hmAux.get(i);
String modelS = model.get(CartaoDao.IDCARTAO);
if (modelS != null) {
if (modelS.equals(myString)) {
index = i;
}
}
}
return index;
}
In the same activity where it has Spinner action I deleted everything and just added:
hmAux = cartaoDao.obterListaCartao();
sp_card.setSelection(getSpinnerIndex(sp_card, String.valueOf(idCartao)));
Being this hmAux of type ArrayList <HMAuxCartao>.
Thanks for the help.
